She's trying to make an official business of the kind of thing she did for Summer & Idol. She wants to professionally assist planning, design, production with any event, space, item, etc.
Okay so I just learned she's still part of the board of &Idol and they are working on their second project with the michelin star restaurant dotonbori akaoni. (Credit to @fryan_get on twitter)
She's also having her own apparel design company with her sister. So I'm wondering where you heard that she's also trying to come through with her own event organizing company? Was this some misunderstanding?
